Ellipticities of 1000 snapshots spanning ∼370 days for a GRMHD model with the following parameters: magnetic field configuration = MAD; thermal eDF; black hole spin = −0.5; R_high=160, R_low=1; and inclination angle = 17^°. The ellipticity of each snapshot is measured after blurring with a 12 μas Gaussian (blue). The median and 68% confidence interval of the time series are shown with a solid green line and shaded region, respectively. The ellipticity of the time-averaged image (right) is shown with a red line.
